plakar

plakar is an open-source backup solution designed to protect files, application data, and contextual metadata in a scalable way. It goes beyond basic file copying by storing data and its surrounding context inside Kloset, an immutable open-source data store. The project focuses on making backups easy to start while still supporting advanced data protection scenarios. It emphasizes security through end-to-end encryption for both backup data and metadata. Plakar is also built for reliability, using immutable storage to reduce the risk of accidental modification or corruption. Its main value is giving users and organizations a practical backup system that combines simple operation, strong protection, and support for large datasets with limited memory usage.
